[Buildroot] [PATCH v3 2/4] lmbench: memsize: increase delay for slow FPGAs

[Yann E. MORIN]

Vineet, All,

On 2021-05-10 11:00 -0700, Vineet Gupta via buildroot spake thusly:

This triple-dash line is the usual git marker to end the actual commit
log, so everything below was dropped when applying the patch with git-am.
I've fixed that, and applied to master, thanks.

However, I wonder how relevant lmbench is nowadays. Indeed, there has
been zero activity on lmbench source code since June 2009, almost 12
years ago now...

Regards,
Yann E. MORIN.
